I tried to post in the last thread, but apparently it had to be approved by a moderator since I had a link to a website in the post. Guess it never got approved.

It seems like Yarde Metals carries 7075-T6 Hex Bar in 0.375" and smaller. No tolerance listed, but I'm sure you could give them a call. A lot of people online seem to buy from them with no issue - the "drop zone" surplus is often pretty cheap.
